3.5 Brakes
Service brake
Hydraulically actuated center-mounted disk brake, combined with
hydrostatic brake of travel drive.
Brake acts on all 4 wheels via 4-wheel drive.
Parking brake
Mechanically actuated center-mounted disk brake at front axle.
Additional brake
The hydrostatic travel drive in closed circuit additionally acts as
non-wearing service brake.
3.6 Hydraulic system
Hydraulic pump
Gear pump on throughdrive of variable displacement pump.
Pump capacity: max. 64 l/min.
Working pressure, steering: 175 bar
Working pressure, loading: 250 bar
Priority valve
Priority supply of hydraulic oil to steering through
load-sensing
system, ensuring that all the available oil can be provided if
necessary. Rapid steering movements even at low engine revs.
Steering
Fully hydraulic, proportionally acting articulated steering.
One steering cylinder with end-position damping at both ends.
Total steering angle
80°
Loader installation
Parallel kinematics
Double-acting work cylinders, one lift cylinder, and one tilt cylinder.
Z kinematics
Double-acting work cylinders, two lift cylinders, and one tilt
cylinder.
Hydraulic
proportionally-actuated
control valve with 3 control
circuits. Work functions:
“Lift / lower”, “Dump / tilt-back”, “Additional
control circuit”.
Third control circuit as fingertip control, electro-proportional
control, oil flow limited via potentiometer, continuous operation
circuit, installation on loading frame incl. plug-in couplings.
Hydraulically-operated
float position for the
"Lower"
work function
if "lowering" pressure point on joystick is exceeded, electrically-
activated locking effect for continuous
"Float"
operation.
Single, four-way control lever (joystick) with integrated travel
direction switch and switch for additional control circuit.
Additional control circuit
Max. oil flow
64 l/min
Max. operating pressure 230 bar
Hydraulic oil cooler
Thermostatically controlled.
